Bezier Curve Extrusion

I have been looking for a way to extrude a Mesh Circle down the path made by a Bezier curve i no it can be done in Auto Cad but i was wondering if it can be done in blender and if so then How??? plz help me out with this.

Create the two curves, one the path(a bezier curve) and the other the profile. Notice the name of the profile curve.

Select the path curve and press F9 to get to the Edit buttons. Type the name of the profile curve in the BevOb field and presto! Thats it. You can also use another curve to taper the curve path by using the TaperOb field.

Here’s a quick video demonstrating the process:
